crossfire help! only 1 gpu is working

[the4ork]

i play 2 games, this game and starcraft 2

i have rivatuner installed for hardware monitoring and my 2nd gpu is at 0% all the time and my primary gpu only gets up to about 70-80% but yet the game struggles sometimes and fps drops below 20 frequently (when diving at the ground)

id like to have my 2nd gpu working. it works in starcraft 2 just fine and both are running in the 90% or higher area

im running the latest ati drivers and crossfire profiles but there is no ah2 profile. ive tried it on default, 1x1, afr friendly...

sigh...

In order for Crossfire to work with Aces High, you have to have a game profile installed for Aces High.  I am pretty certain AMD/ATI has not made a profile for Aces High.

That's good to know. I was just thinking about this.

I have 2 x 5850 cards, running under a "user-defined application profile."  Within that profile, the CrossFire mode that works best for me is "Optimize 1x1."  And despite asking the question in every forum I can find, I still don't have an answer for *exactly* what that "Optimize 1x1" actually means.  But I deduce from the temperature history I can see in HWMonitor that it is the setting which puts the second card to the most use.

For other apps, download the "AMD Catalyst Application Profiles" from the AMD support site.

YMMV
